2 Kings 15:37In those days the LORD began to send Rezin king of Aram and Pekah the son of Remaliah against Judah.

2 Chronicles 28:5Wherefore, the LORD his God delivered him into the hand of the king of Aram; and they defeated him and carried away from him a great number of captives and brought them to Damascus. And he was also delivered into the hand of the king of Israel, who inflicted him with heavy casualties.

2 Chronicles 28:6For Pekah the son of Remaliah slew in Judah 120,000 in one day, all valiant men, because they had forsaken the LORD God of their fathers.

Isaiah 7:1Now it came about in the days of Ahaz, the son of Jotham, the son of Uzziah, king of Judah, that Rezin the king of Aram and Pekah the son of Remaliah, king of Israel, went up to Jerusalem to wage war against it, but could not conquer it.

Ezekiel 16:57before your wickedness was uncovered, so now you have become the reproach of the daughters of Edom and of all who are around her, of the daughters of the Philistines-- those surrounding you who despise you.

Treasury of Scripture

Then Rezin king of Syria and Pekah son of Remaliah king of Israel came up to Jerusalem to war: and they besieged Ahaz, but could not overcome him.

(5) Then Rezin king of Syria. . .to war.--This verse agrees almost word for word with Isaiah 7:1. The time is soon after the accession of Ahaz. "Jotham, the last of a series of strong and generally successful princes, had died at a critical moment, when Pekah and Rezin were maturing their plans against his kingdom. The opposing parties in northern Israel suspended their feuds to make common cause against Judah (Isaiah 9:21), and the proud inhabitants of Samaria hoped by this policy to more than restore the prestige forfeited in previous years of calamity (Isaiah 9:9-10). At the same time the Syrians began to operate in the eastern dependencies of Judah, their aim being to possess themselves of the harbour of Elath on the Red Sea, while the Philistines attacked the Judeans in the rear, and ravaged the fertile lowlands (Isaiah 9:12, 2Kings 16:6). A heavy and sudden disaster had already fallen on the Judean arms, a defeat in which 'head and tail, palm-branch and rush' had been mown down in indiscriminate slaughter (Isaiah 9:14). Ahaz was no fit leader in so critical a time; his character was petulant and childish, his policy was dictated in the harem (Isaiah 3:12). Nor was the internal order of the state calculated to inspire confidence. Wealth, indeed, had greatly accumulated in the preceding time of prosperity, but its distribution had been such that it weakened rather than added strength to the nation. The rich nobles were steeped in sensual luxury, the court was full of gallantry, feminine extravagance and vanity gave the tone to aristocratic society (Isaiah 5:11; Isaiah 3:16; comp. Isaiah 3:12; Isaiah 4:4), which, like the noblesse of France on the eve of the Revolution, was absorbed in gaiety and pleasure, while the masses were ground down by oppression, and the cry of their distress filled the land (Isaiah 3:15; Isaiah 5:7)."--Prof. Robertson Smith.

They besieged Ahaz.--The allies wanted to compel Judah to join them in their attempt to throw off the burdensome yoke of Assyria, imposed in 738 B.C. (2Kings 15:19); and thought the best way to secure this was to dethrone the dynasty of David, and set up a creature of their own--"the son of Tabeal" (Isaiah 7:6).

Could not overcome him.--Literally, they were not able to war, as in Isaiah 7:2. The allies could not storm the city, which had been strongly fortified by Uzziah and Jotham (2Chronicles 26:9; 2Chronicles 27:3).

Verses 5, 6.- War of Ahazleith Pekah and Rezin. Verse 5. - Then Rezin King of Syria and Pekah son of Remaliah King of Israel came up to Jerusalem to war. The alliance between Rezin and Pekah has been already glanced at (2 Kings 16:37). It began, apparently, in the reign of Jotham. The policy which brought it about was one that was entirely new. Since Syria developed an aggressive tendency under the first Ben-hadad (1 Kings 20:1), there had till now been no alliance made with her by either of the two Israelite kingdoms. She had been reckoned as their common enemy; and while they had on two occasions been allied together against her (1 Kings 22:4-36; 2 Kings 8:28), never as yet had either asked her help against the other. Now, however, Ephraim became confederate with Syria against Judah. The new policy must be ascribed to the new condition of things consequent upon the attitude assumed by Assyria under Tiglath-pileser. Assyria had been under a cloud for forty years. The nations of the western coast of Asia had ceased to fear her, and had felt at liberty to pursue their own quarrels. Her recovery of vigor altered the whole situation. It was at once evident to the statesmen who directed the policy of the small western states that, unless they combined; they were lost. Hence the alliance between Pekah and Rezin. Probably they would have been glad to have drawn Ahaz into the confederacy; but it would seem that he did not share their fears, and would not join them. Hereupon the design was formed to dethrone him, and set up in his place a new ruler, a certain Ben-Tabeal (Isaiah 7:6), on whose assistance they could rely. The two confederate princes then began the campaign. Pekah invaded Judaea, and gained a great victory over Ahaz, which is perhaps exaggerated in 2 Chronicles 28:6-15; Rezin carried his arms further south, took Elath, and reestablished the Edomites in power (see the comment on ver. 6). Then the allies joined forces and proceeded to besiege Jerusalem. And they besieged Ahaz, but could not ever-come him. The siege is mentioned by Isaiah 7:1, who was commissioned by God to comfort Ahaz, and assure him that the city would not fall (Isaiah 7:7). The fortifications of Uzziah (2 Chronicles 26:9) and Jotham (2 Chronicles 27:3) had, no doubt, greatly strengthened the city since the time when (as related in 2 Kings 14:13) it was captured so easily by Joash.

Then Rezin king of Syria, and Pekah son of Remaliah king of Israel, came up to Jerusalem to war,.... To fight with Ahaz, moved to it by the Lord, to chastise Ahaz for his idolatry, 2 Kings 15:37.

but could not overcome him; so as to take Jerusalem, and set up another king there, as their scheme was, Isaiah 7:5 though they had both at other times got great advantages over him, and slew many of his people, and carried them captive, see 2 Chronicles 28:5.

5. Then Rezin king of Syria and Pekah son of Remaliah king of Israel came up to Jerusalem—Notwithstanding their great efforts and military preparations, they failed to take it and, being disappointed, raised the siege and returned home (compare Isa 7:1).

16:1-9 Few and evil were the days of Ahaz. Those whose hearts condemn them, will go any where in a day of distress, rather than to God. The sin was its own punishment. It is common for those who bring themselves into straits by one sin, to try to help themselves out by another.
